The Jack API documentation says port_registration_callback is supposed to be called on port register AND deregister, but it only seems to be called when a port is registered.
So essentially, how can an app know when a jack port is deregistered? In case you're wondering, I'm writing a modular jack patch bay, this is the last hurdle before pre-release. So, uh, if you want a modular jack patch bay, help a brother out. :) (I would post this to jack-devel, but the server is giving me nonsense and not letting me register) -Dave
